I have written a book in collaboration with João P. Silva on quantum field theory at an introductory level Quantum Field Theory. In this text I present many programs both for Mathematica or Fortran. In this section I provide a link to program file and the reference for the page on the book (last updated on 09/12/2024 to be compatible with FeynCalc 10.1.0). The mathematica programs for FeynCalc can be easily tested with the notebook Examples.nb. To work all the programs must exist in the same directory. For convenience you can find here a zip of all the programs needed to run Examples.nb.
